Step produces the generator of electric power.Lead battery can be as the specific example of battery 11.
Igniting of off-state from the ignition switch 21 to 1 output indication ignition switch 21 of control device or on-state is believed
Number.
Current measuring unit 22 is the exemplary means for the electric current (battery current) that battery 11 is flowed through in measurement.Current measurement list
Member 22 is, for example, that detection flow to the charging current of battery 11 or the current sensor of the discharge current flowed out from battery 11.
Temperature measurement unit 23 is showing for temperature (battery temperature) around the temperature or battery 11 of measurement battery 11 itself

Control device 1 is, for example, with charging control unit 31, charge rate computing unit 32 and charge rate correction unit 33
Electronic device.In control device 1, (including the deterioration described below determines unit such as charging control unit 31
Unit 41 etc.) for example realized by the microcomputer equipped with central processing unit (CPU).
Charging control unit 31 is to perform the exemplary electrostatic electric unit of following charging operations, and the charging operations are used to pass through
Charge to battery 11 until battery 11 receive electric current I less than the charging ending phase of predetermined current value Ith untill press down
The deterioration of battery 11 processed.This charging operations will be referred to as refresh charge below.In addition, it is to flow to battery 11 to receive electric current I
Charging current.
Refresh charge be under the charge condition with constant low current and constant high voltage by relatively long charging when
Between (for example, 30 minutes or more) battery is charged into relatively high charge rate (for example, SOC=95% or more).
By way of parenthesis, the charged state (SOC) for representing the charge rate of battery is, for example, to be defined (residual capacity (Ah)/complete
Charging capacity (Ah)) × 100 (%)) value.
It can become to deteriorate to suppress battery 11 by performing refresh charge.For example, in the case of lead battery, due to sulphur
Sour salinization makes sulfuric acid leading crystal be deposited on the positive plate and negative plate of battery 11, and the absolute capacity of battery 11 reduces, because
This battery 11 further deteriorates.However, it is possible to decompose and remove sulfuric acid leading crystal by performing refresh charge.Therefore, can be with
Suppress battery 11 further to deteriorate due to sulfation.
Charge rate computing unit 32 is the example calculation unit for the charge rate for calculating battery 11.Charge rate computing unit 32
Calculate the SOC of such as battery 11.
Charge rate correction unit 33 is come to being counted by charge rate computing unit 32 based on the behavior for receiving electric current I of battery 11

Known charge receive characteristic, based on the behavior (changing with time) for receiving electric current I measured by current measuring unit 22 come
Correct the SOC of battery 11.Charging is by the characteristic that characteristic is the relation that instruction receives between electric current I and SOC.Charge rate correction is single
Member 33 is using for example representing data of the charging measured in advance on battery 11 by characteristic.
Fig. 2 is (to carry out school using electric current I is received based on the behavior for receiving electric current I of battery 11 to correct the SOC of battery 11
The sequence diagram of illustrative methods just).Fig. 2 shows to charge to battery 11 is less than predetermined current value until receiving electric current I
Process untill the charging ending phase of Ith.Before state of the battery 11 in the ending phase that charges is fully charged state
Substantially completely charged state (for example, SOC=90% or more).
For example, when battery 11 passes through relatively long charging under the charge condition with constant low current and constant high voltage
When time is charged and then reaches substantially completely charged state, the current value for receiving electric current I reduces rapidly, and
The electric current I that receives at moment t11 and after moment t11 decreases below predetermined current value Ith.Then, at moment t11
And after moment t11, when continuing to charge to battery 11 under identical charge condition, receive the current value of electric current I
Change rate become equal to or less than predetermined rate of descent, and the change rate of SOC becomes equal to or less than predetermined climbing.
Battery 11 has following charging by characteristic：Decreasing below current value Ith's (such as 3A) from receiving electric current I
Moment t11 is risen at the time of when passing through Time constant Tth (such as 2 minutes) at t12, and SOC is equal to constant S1 (such as 95%).
Therefore, charge rate corrects unit 33 under the charge condition with constant low current and constant high voltage by opposite
The long charging interval charges battery 11, and from receiving electric current I and decreasing below current value Ith by it is constant when
Between Tth when carry out using constant S1 replace SOC current value correction.In the case of figure 2, charge rate correction unit 33 carries out
Correct below：SOC is rearranged into from SOC before the correction at moment t12 at moment t12 and offset by the correction of offset a
SOC (=constant S1) afterwards.
In this way, charge rate correction unit 33 can be corrected with high accuracy school by using electric current I is received
The charge rate of positive battery 11.Then, using receiving after electric current I is corrected, charge rate correction unit 33 can also pass through
Come to correct the charge rate at moment t12 and after moment t12 with high accuracy below：For by using receiving electric current
SOC continues another correction after the correction that the correction of I is obtained, such as integration of charge/discharge current to battery 11 etc..
In addition, charge rate correction unit 33 can be corrected using receiving electric current I appropriate at the time of by following：
Based on receiving the behavior of electric current I and refresh charge synchronously corrects the charge rate of battery 11 in charging ending phase.This is because：
By the refresh charge of the deterioration for suppressing battery 11, the state of battery 11 can be transferred to for using receive electric current I into
Substantially completely charged state needed for row correction.
Therefore, by making to obtain for example following effect using the correction of electric current I and refresh charge is received synchronously：So that really
Protect the standard of charge rate of the chance for the control operation that the opposite rapid fluctuation of charged state to battery performs with improving correction battery
Exactness is coordinated with each other.For example, can prevent from making battery charged state limited with respect to the control operation of rapid fluctuation it is (also banned
Only) it is only used for utilizing the correction for receiving electric current I.Furthermore, it is possible to receiving is utilized for example before the remarkable progress of the deterioration of battery
Electric current I is corrected, therefore can accurately and continuously correct the charge rate of battery.
By way of parenthesis, such as controlling charge control, stopping and the starting control (S＆S of voltage are produced by alternating current generator
Control) etc. can be used as the control operation of charged state to battery rapid fluctuation relatively.S＆S controls are to meet predetermined stop
The control for making engine temporarily cease and reset engine when meeting predetermined starting conditions during condition.
In Fig. 1, control device 1, which has, for example deteriorates determination unit 41.Deterioration determination unit 41 is to determine battery 11
The exemplary determination unit of degradation.Determination unit 41 is deteriorated based on evaluable index to determine the degradation of battery 11.
For example, aggregate-value, the idle stop of engine 26 of the number of the idle stop of engine 26 on vehicle 100
The aggregate-value of time, the aggregate-value of the discharge capacity of battery 11, the slippage of voltage etc. of battery 11 can be used as such index.
When the degradation determined by deterioration determination unit 41 reaches predetermined threshold th, charging control unit 31 performs brush
New charging.When performing refresh charge, the degradation of battery 11 is initialised.When degradation reaches predetermined threshold th,
Perform refresh charge.Therefore, charge rate correction unit 33 can reach predetermined threshold th with degradation and synchronously be utilized
Receive the correction of electric current I.Therefore, corresponding it can it is expected that moment place is electric using receiving in the progress extent of the deterioration with battery 11
Stream I is corrected, wherein, nearest refresh charge at the time of, is considered as starting point.
Fig. 3 is the sequence diagram of the illustrative methods for the charge rate for showing correction battery 11.Period t1 to t2, t3 to t4 and
Each in t5 to t6 is the period that ignition switch 21 is connected.Each in period t2 to t3 and t4 to t5 is that igniting is opened
Closed for 21 periods disconnected.B and B' represents to utilize the correction for receiving electric current I.At the time of t1 is into t2 in the period brush is performed at t7
B is corrected during new charging.B' is corrected when performing refresh charge at t8 at the time of t5 is into t6 in the period.
Charge rate corrects unit 33 based on for example following correction value deltas to correct the charge rate of battery 11, which is
Based on receiving the behavior of electric current I in the ending phase that charges and refresh charge synchronously calculates.For example, in the context of fig. 3,
Correction value delta is calculated at moment t7, and correction value delta is recalculated at moment t8.It is in degradation in correction value delta
In the case of being calculated before reaching threshold value th, charging control unit 31 does not perform refresh charge.If for example, in ignition switch 21
The period t3 of connection degradations into t4 are not up to threshold value th, then do not perform refresh charge, therefore, also without utilizing receiving
The correction of electric current I.Accordingly it is possible to prevent unnecessarily carry out utilizing the correction for receiving electric current I.
If due to correction value delta be calculated before degradation reaches threshold value th and be not carried out refresh charge, fill
Electric rate correction unit 33 based on the correction value delta synchronously calculated with refresh charge that is performed before the nearest time come
The current charge rate obtained by charge rate computing unit 32 is corrected.For example, charge rate correction unit 33 was based at the moment
The charge rate at the time of correction value delta calculated at t7 is come to from moment t7 to subsequent calculating correction value delta in the period of t8 carries out
Correction.Therefore, can also be based on the correction value delta being computed even if not calculating correction value delta due to not performing refresh charge
To continue to correct charge rate with high accuracy.
Correction value delta is according to the difference between the first calculated value α 1 of such as charge rate and the second calculated value α 2 of charge rate
Value D and definite value, wherein, the first calculated value α 1 is based on receiving the behavior of electric current I in the ending phase that charges and refreshing is filled
What electricity synchronously calculated, the second calculated value α 2 is the electricity based on battery 11 at the about the same time for calculating the first calculated value α 1
Press and calculate.That is, the second calculated value α 2 be based on the voltage of battery 11 in charging ending phase, the voltage based on battery 11 with
The rule of relation between charge rate and the charge rate calculated.Correction value delta may, for example, be the value equal to difference D or lead to
Cross value obtained from difference D is multiplied by predetermined ratio constant.
Therefore, charge rate correction unit 33 can make following correction：For example, the current charge rate of battery 11 is set again
It is set to the charge rate that is calculated by adding to correction value delta by charge rate computing unit 32 or from by charge rate computing unit 32
The charge rate of calculating subtracts value obtained from correction value delta.
Charge rate correct unit 33 based on correction value delta come to by charge rate computing unit 32 according to such as following methods meter
The charge rate of calculation is corrected, and this method is different from same based on the behavior and refresh charge for receiving electric current I in charging ending phase
The method that step ground calculates charge rate.
The aggregate-value of amount of charge/discharge based on battery come calculate the method for charge rate can as calculate charge rate not
With the specific example of method.As an alternative, can mention based on the ignition switch of vehicle disconnection in the state of cell voltage with
And the aggregate-value of the amount of charge/discharge of the battery in the state of ignition switch calculates the method for charge rate.
Voltage of the charge rate computing unit 32 based on the battery 11 under 21 off-state of ignition switch, based on such as battery
The rule of relation between 11 voltage and charge rate calculates the charge rate β of battery 11.A in Fig. 3 is represented according to battery electricity
Pressure calculates charge rate β.Then, charge rate correction unit 33 corrects charge rate β by following：It will be surveyed by current measuring unit 22
The aggregate-value (Ah) of the battery current of amount adds to remaining appearance for example corresponding with the charge rate β calculated by charge rate computing unit 32
Amount (Ah) is subtracted by electric current from residual capacity (Ah) for example corresponding with the charge rate β calculated by charge rate computing unit 32
The accumulated value (Ah) for the battery current that measuring unit 22 measures.C in Fig. 3 represents to correct charging by integrating battery current
Rate β.In addition, charge rate corrects unit 33 based on correcting charge rate β using the correction B of electric current I is received.
Even if such as current measuring unit 22 can not integrate electric current in the state of the disconnection of ignition switch 21, also may be used
To continue the charge rate of correction battery 11 with high accuracy in a long time by combining multiple bearing calibrations in this way.
In Fig. 1, control device 1, which can have, replaces detection unit 42, which is based on for example can
